Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_182894.3(VSX2):c.71dup(p.Ala25ArgfsTer102) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000429 in 1,398,800 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. S22S) has been classified as Likely benign.

Isolated microphthalmia 2 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 31, 2023 | This premature translational stop signal has been observed in individual(s) with VSX2-related conditions (PMID: 24033328). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 221962). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ala25Argfs*102) in the VSX2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in VSX2 are known to be pathogenic (PMID: 20414678). - |
